class

问题 I want to measure dependencies between classes - what's the best approach and tools to use? I'm working in MS .Net Text based information / reports are OK, but I'd prefer something visual. Open source tool would be ideal. 回答1: This may not help (right now), but it looks like VS 2010 will have a dependency graph feature out of the box. Looks like it will do class, namespace, and assembly dependencies. 来源： https://stackoverflow.com/questions/2376519/measuring-class-dependencies

问题 How do I inject objects at runtime? For example, if I want to inject DerviedOne, DerivedTwo objects at runtime into the Test class in the following example, how do I do that? I found a few examples in Spring, but I'm not using Spring. This is a Dynamic Web Project with CDI using Java EE 6. public abstract class Base { public Base(String initiator) { this.initiator = initiator; } public abstract void process(); public void baseProcess() { System.out.println("base process"); process(); } public

问题 i have the following code in a module called code_database.py class Entry(): def enter_data(self): self.title = input('enter a title: ') print('enter the code, press ctrl-d to end: ') self.code = sys.stdin.readlines() self.tags = input('enter tags: ') def save_data(self): with open('entry.pickle2', 'ab') as f: pickle.dump(self, f) in idle the class-defined methods work fine: >>> import code_database >>> entry = code_database.Entry() >>> entry.enter_data() enter a title: a enter the code,

问题 According to this question/answer in stackoverflow, it is not possible to directly rewrite C++ nested typedefs in cython. I have such a problem and I don't know which is the right/optimal way to proceed. Let me be more specific with an example. Below, you can find the content of two C++ files (one header.h and one .cpp) and of two corresponding cython files (one .pxd and one .pyx). In the C++ header file called cpp_graph.h you can see nested typedef declarations; for example, that

问题 I want to make a class to group some static const values. // SomeClass.dart class SomeClass { static const SOME_CONST = 'some value'; } What is the idiomatic way in dart to prevent dependent code from instantiating this class? I would also like to prevent extension to this class. In Java I would do the following: // SomeClass.java public final class SomeClass { private SomeClass () {} public static final String SOME_CONST = 'some value'; } So far all I can think of is throwing an Exception ,

问题 I want to create an error class. And it has some static properties. For example : Message , InnerException , Stacktrace , Source . But I want to add some dynamic properties. If exception is a FileNotFoundException , I want to add FileName property. Or if it is a SqlException , I want to add LineNumber property. And I can't inherit that class from Exception because, I return that class from a web service. How can I do that? 回答1: you can create type dynamically using new features in C# like

问题 I have to access and write to some berkeley db files that other applications share. I really haven't found anything out there about using this with PHP. It really doesn't seem very popular. Does anyone have any links or resources that I might be able to use to get things rolling? Thanks! 回答1: Isn't this what the dba functions are for? http://php.net/manual/en/book.dba.php I've had some code some years ago with that. Didn't use it much however, because it was a somewhat inefficient data store.

问题 I am in the process of writing an API for my website, along with a pretty large class to process all of the API requests. Most pages, if not all all the pages on the website will send at least one request to the api on load. The most important priority for this website is efficiency and resultantly, very quick server processing. I am therefore seeking a little bit of advice when it comes to classes and certain PHP functions. Firstly, it looks like the class I am writing will probably end up
